Remanufacturing a Ford/IH 6.9L Diesel engine involves many steps and manipulation of certain components to complete the process. Below you'll see the components that are contained within the engine and how those components are handled by us during the remanufacturing process. Think of them as the steps towards a quality engine.

Engine Block/Case
The rebuilding process starts at the bare cylinder block/case. Every engine is stripped down to the bare block to examine it carefully to determine whether or not it will be suitable for rebuilding.

Upgrades & Options


Beyond the OEM oriented rebuild offered above several upgrades and options are available. Many of the upgrades and options offered below are geared at either improving the overall durability of the engine or to improve power output, and in many cases both.

Balancing
A true balancing of the rotating assembly is a highly recommended upgrade for any engine.

The Balancing is completed using a Multi-Bal 3000 balancer that uses computer software to analyze the crankshaft with calibrated bob weights. The Bob weights are used to simulate the same weight as the other components of the rotating assembly.

Benefits...
  • Smoother Running
  • Reduced Crank Fatigue
  • Longer Crank Life
  • Reduced Internal Wear
  • Increased Power

In Order to complete the balancing the majority of the engine's rotating assembly components must be modified.

Components Modified...
  • Match Piston Weight
  • Match Rod Weight
  • Modify Crank Throws




Cyl. Head Porting
Cylinder Head Porting and Gasket Matching can be an added edge towards improving power output. Removing unnecessary material from both the intake and exhaust ports of the cylinder heads helps airflow into and out of the engine. By increasing air volume through the engine, the overall potential for increased power output is improved.

Depending on the need, a gasket/port match, port blend, or full porting may be peformed.

Benefits...
  • Increased Power
  • Lower EGT's
  • Less Black Smoke
  • Better Fuel Economy



Lower Compression Ratio
Lowering the effective compression ratio of the 6.9 engine is a method of increasing durability of the engine while running at higher than designed power levels. There are many different ways of lowering the compression ratio of an engine. The method used here is by reducing the piston's height. The only disadvantage to this modification is cold starting ability, which can be overcome with either intake heaters, quick heat glow plugs, or extended glow and afterglow times.

Benefits...
  • Safer At High Power
  • Increase HP Potential
  • Increase TQ Potential
  • Allows for More Boost
  • Allows for More Fuel
  • Best Head Gasket Life
  • Less Block Stress
  • Less Crank Stress
  • Decreased Wear



ARP Head Studs
ARP's head studs provide greater clamping force between the block and the cylinder head and are a performance oriented upgrade.

Benefits...
  • Less Gasket Failure
  • Better Clamping
  • Stronger
  • Re-usable



Ceramic Coatings
High Temperature Ceramic Coatings can be applied to a number of components that are subjected to the extreme temperatures associated with engine combustion. The coating is designed to reflect heat away from the component that it is applied to, thus providing a protective layer for the component.

Items To Protect and Coat...
  • Piston Crowns
  • Head Exhaust Ports
  • Head Exhaust Bowls
  • Head Chamber
  • Pre-chamber & Cup
  • Intake Valves
  • Exhaust Valves
  • Exhaust Manifold
  • Exhaust Manifold Ports

Most of the uses of ceramics are for the protection of the engine components to help them resist the heat that can destroy them. In some instances, ceramics can also be applied to protect external components such as exhaust manifolds and headers against rust, and insulate heat away from the engine.

Benefits...
  • Heat Rejection
  • Increased Engine Life
  • Less Part Cracking
  • Less Coolant Temp
  • increased component life


Beyond Longblock
Bolt-on accessories and upgrades are available. These items can be installed before your engine is shipped to aide in the installation of the new engine into the chassis.

Thinking Beyond The Long Block...
  • Reman Injectors
  • Injection Pump MFI
  • Inj. lines & brackets
  • Valvecovers
  • Lift Brackets
  • Injector Return Lines
